First, the use of products
Polyol drilling fluid is a nonionic surfactant, non-toxic tasteless, non corrosive, insoluble in water, with the characteristics of cloud point. Strong inhibition, good stability of the borehole wall, good lubrication, low damage to the oil and gas reservoirs, biodegradable, little impact on the environment.

Two, technical requirements
 

Project		Requirement
		Ⅰtype	Ⅱtype	Ⅲtype
Appearance		Uniform transparent liquid, no precipitation
Water solubility		Not stratified

Three, the use of methods
The reference dosage was 3 ~ 5%.

Four, storage and transportation
1 products stored in ventilated, dry place, prevent direct sunlight.
2 transport and handling should be light light unloading, packaging to prevent breakage.

Five, matters needing attention
In the use of the process, the staff should wear masks, wear chemical safety glasses, wear anti-static work clothes. Prevent products from entering the eyes or in contact with the skin, once the occurrence of the above situation, with water or saline flush, the situation is serious and timely medical treatment.
